Who are the founders of Bitcoin (BTC)? 

Bitcoin was created by an individual or group of individuals under the pseudonym Satoshi Nakamoto. The true identity of Satoshi Nakamoto remains unknown. The concept of Bitcoin was introduced in a white paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" published on October 31, 2008. This paper proposed a decentralized digital currency that would eliminate the need for trust or centralized institutions for financial transactions.

The first Bitcoin software was released to the public in January 2009, and Nakamoto mined the first block of the Bitcoin blockchain, known as the genesis block, starting the new era of cryptocurrency. The creation of Bitcoin was motivated by the desire to produce a means of exchange that was independent of any central authority, and could be transferred electronically in a secure, verifiable, and immutable way.

How has Bitcoin (BTC) changed since its inception?

Since its inception, Bitcoin has seen significant developments and changes. Here are some key moments in its evolution:

• Introduction of the Blockchain: The underlying technology of Bitcoin, blockchain, introduced a decentralized ledger that records all transactions across a network of computers.
• First Real-world Transaction: In May 2010, Laszlo Hanyecz made the first known purchase using Bitcoin, buying two pizzas for 10,000 BTC, highlighting its potential as a means of exchange.
• Halving Events: Bitcoin experiences a halving approximately every four years, which reduces the reward for mining new blocks by half. This mechanism, designed to control inflation, has significant implications for its value and miners' activity.
• Significant Updates: Bitcoin has undergone various updates to improve its scalability, security, and performance. Notable updates include Segregated Witness (SegWit) in 2017, which increased block capacity and laid the groundwork for future Layer 2 solutions like the Lightning Network.
• Forks: Bitcoin has experienced several forks, leading to the creation of new cryptocurrencies. The most significant one was Bitcoin Cash in 2017, which addressed concerns about Bitcoin's scalability by increasing the block size.

Adoption and partnerships 

Bitcoin's adoption has grown exponentially over the years. Initially perceived as an internet oddity, it has gained recognition as a legitimate asset class by investors, businesses, and governments.

• Institutional Adoption: Financial institutions, hedge funds, and corporations have started to acknowledge Bitcoin as a store of value and an investment asset, with some adding it to their balance sheets or offering Bitcoin-related investment services.
• Retail Adoption: The acceptance of Bitcoin for payments has increased, with companies across various industries, from technology to hospitality, allowing customers to make transactions using BTC.
• Partnerships and Collaborations: While Bitcoin itself, as a decentralized network, doesn't form partnerships in the traditional sense, various companies and platforms have built services and solutions around it, enhancing its ecosystem. These include cryptocurrency exchanges, trading platforms, wallet providers, and payment processors.
• Government and Regulatory Engagement: Several countries have begun to explore regulatory frameworks for Bitcoin, acknowledging its presence and importance in the financial landscape. Some have gone further, adopting it as legal tender, such as El Salvador in 2021.

Bitcoin's journey from an obscure digital currency to a widely recognized financial asset highlights its profound impact on the financial world. Despite challenges such as volatility, regulatory scrutiny, and technical debates, Bitcoin continues to play a pivotal role in the evolving landscape of digital currencies and blockchain technology.

Underlying technology

Bitcoin is built on blockchain technology, a decentralized ledger that records all transactions across a network of computers. This technology ensures security, transparency, and integrity in the transaction process without the need for a central authority.

• Blockchain: At its core, the Bitcoin blockchain is a public, distributed ledger composed of blocks that contain a list of transactions. Each block is connected to the previous one through a cryptographic hash, forming a chain. This structure makes the blockchain tamper-resistant, as altering any information in a previous block would require changing all subsequent blocks, which is computationally impractical due to the network's design.
• Consensus Mechanism: Bitcoin uses a Proof of Work (PoW) consensus mechanism to validate transactions and add new blocks to the blockchain. Miners compete to solve complex cryptographic puzzles, and the first to solve the puzzle gets the right to add the new block to the chain. This process not only secures the network and validates transactions but also creates new bitcoins as a reward to the successful miner, known as the block reward.

How are Bitcoin (BTC) tokens created and distributed?

• Mining: The primary method of creating and distributing Bitcoin tokens is through mining, a process tied to the maintenance and development of the blockchain. Mining involves using computational power to solve cryptographic puzzles that validate transactions and create new blocks.
• Supply Limits: Bitcoin's design includes a fixed supply limit of 21 million coins. This cap is intended to prevent inflation and mimic the scarcity and value preservation of precious metals like gold. The supply limit is enforced through the halving events that occur approximately every four years, where the block reward for miners is cut in half. This mechanism slows the rate of new Bitcoin creation and will continue until the last Bitcoin is mined, expected around the year 2140.
• Halving Events: These events are significant because they reduce the rate at which new bitcoins are generated, affecting supply and potentially influencing Bitcoin's price. The halving is programmed into Bitcoin's code and occurs every 210,000 blocks.
• Distribution: Bitcoin is distributed directly to miners as a reward for validating transactions and securing the blockchain. Initially, the reward was 50 BTC per block, but as Bitcoin underwent halvings, the block reward was significantly reduced. Currently, the block reward is 6.25 BTC (As of February 12th, 2024); after the next halving the block reward will be 3.125 BTC.
• Staking Mechanisms: Unlike some cryptocurrencies that use Proof of Stake (PoS) for consensus, Bitcoin solely relies on PoW for its operation and does not offer a staking mechanism.

What are the main use cases of Bitcoin (BTC)? 

Bitcoin, as the first and most widely recognized cryptocurrency, has several primary use cases, illustrating its versatility and the broad appeal it has garnered over the years. Here are some of its main applications:

• Digital Gold: One of the most prominent use cases of Bitcoin is as a form of digital gold. It is seen as a store of value and a hedge against inflation, much like traditional gold, due to its limited supply and decentralized nature.
• Medium of Exchange: Bitcoin is used as a medium of exchange for goods and services. With its increasing acceptance by merchants and businesses worldwide, it allows for direct, peer-to-peer transactions without the need for intermediaries.
• Cross-Border Transactions: Its ability to facilitate fast and relatively low-cost transactions across borders makes Bitcoin an attractive option for remittances and international trade, bypassing traditional banking channels and exchange rates.
• Investment Asset: Bitcoin has become a popular investment asset, with individuals and institutions investing in it for potential long-term gains.
• Financial Freedom and Inclusion: Bitcoin provides an alternative financial system for unbanked or underbanked populations worldwide, offering access to financial services without the need for traditional banking infrastructure.

Real-world adoption of Bitcoin (BTC) 

The adoption of Bitcoin has been growing steadily, with various sectors and industries recognizing its potential. Here are some examples of real-world adoption and potential future uses:

• Retail Payments: Many online and brick-and-mortar stores now accept Bitcoin as a payment method. Companies like Overstock, Newegg, and even some restaurants and cafes, have started accepting Bitcoin, facilitating its use in everyday transactions.
• Institutional Investment: Financial institutions and corporations have begun investing in Bitcoin, viewing it as a viable asset class. Notable examples include MicroStrategy, which has invested billions in Bitcoin, and Tesla, which purchased $1.5 billion worth of Bitcoin in early 2021.
• Legal Tender: In a landmark move, El Salvador became the first country to adopt Bitcoin as legal tender in September 2021. This decision marks a significant step toward Bitcoin's acceptance and use in everyday financial transactions and could pave the way for other countries to follow suit.
• Philanthropy and Donations: Non-profit organizations and charities have started accepting Bitcoin donations, recognizing the ease and efficiency of cryptocurrency transactions. This includes well-known organizations like the Wikimedia Foundation and the Electronic Frontier Foundation.
   

Bitcoin asset statement 

• Decentralization: As a standout feature, Bitcoin provides independence and near-total censorship resistance from central authorities. This attribute boosts financial freedom by allowing direct transactions between two parties.
• Transparency and Security: Each transaction, once recorded, becomes immutable, enhancing security while offering full transparency in terms of transaction history through public ledger accessibility.
• Finite Supply: A restricted maximum supply cap of 21 million enhances its potential for ever-increasing purchasing power accruing to its holders. This mirrors the theory behind holding physical gold as a hedge against the loss of purchasing power in holding government currencies.
• Financial Freedom: Bitcoin empowers individuals to have full control over their money without the need for intermediaries like banks, enabling near-instant and low-fee transactions (compared to traditional banking systems).
• Hedge Against Inflation: With a limited supply, Bitcoin is seen as a potential hedge against inflation and economic uncertainties, largely increasing or preserving its value over time.
• Borderless Transactions: Bitcoin enables frictionless cross-border transactions, reducing the complexities and costs associated with international transfers.

It is an open accounting system connected by thousands of computers (also known as nodes) working together to track the ownership of Bitcoin. Unlike fiat currencies which are usually controlled by national governments and central banks that govern the money supply, blockchain functions without a centralized authority like a government, central bank, or financial institution.

• Bitcoin is decentralized meaning there is no one computer, person or institution that holds the ledger. With Bitcoin, every computer in the network is also keeping a copy of the ledger (also known as the blockchain).
• Every Bitcoin transaction is broadcast to everyone on the network. After the transactions have been verified, they are recorded in the public ledger.
• Bitcoin is issued to users on the system who help process transactions on the network, this is known as Bitcoin mining.
• Bitcoin miners are users of the system with highly specialized computers that verify and record transactions on the blockchain.
• Miners earn Bitcoin as a reward for their work updating and maintaining the blockchain. This is how new Bitcoins are created and enter into circulation. The rewards for mining new blocks in the blockchain have systematically and steadily dropped over time.
• The standard set of rules and procedures that goes along with tracking the transactions and keeping the ledger by all of the users in the mining process is known as the network's protocol.
• The total number of bitcoins that will be mined has a cap of 21 million. This makes Bitcoin unique compared to traditional fiat currencies (and some other cryptocurrencies) that do not have a specified limit.
• The limit of 21 million Bitcoin creates a level of scarcity for the digital currency, which simply means that in theory, they will be in short supply.
• This has led many to speculate that Bitcoin will be a better store of value compared to fiat currencies over a long period of time. The price of Bitcoin has soared to levels of over $20,000 in Dec. 2017, compared to a price of $0.003 in Mar. 2010.
• Because Bitcoin is transferred from person to person (known as peer-to-peer) using the internet without going through a bank or other financial intermediary, their transaction fees are normally much lower compared to traditional financial instruments like credit and debit cards.
• You can use Bitcoin in any country. This means that for the first time, nearly 2.5 billion unbanked people in the developing world will have access to a financial platform.
• Bitcoin allows users to become anonymous. By encrypting the blockchain using cryptography, it is not possible to know who is involved with the transactions. For these reasons, Bitcoin is referred to as a cryptocurrency.
• The digital currency was created by someone (or possibly a group of people) known as Satoshi Nakamoto in 2009.
• Bitcoin's blockchain is now considered the first generation of the technology.
